Fossil fungi were found from the Pleistocene plants deposits of Shiobara, Tochigi Pref., Japan. They are considered to be epiphyllous fungi. Some of them are impression fossils remaining their epiphyllous habitats on their host leaves. A Phycomycete species is nonpetrified and it might be a recent fungus. The other fungi are petrified. We assigned some of the fungi to the aquatic hyphomycetes and also some of the other fungi to the plant pathogen. Four of the listed fungi are possibly pathogenic fungi remaining only macroscopic symptoms ; such fossils are considered mainly to be helpful for the field survey as an indicator of the occurrence of more important fossil fungi. Thirty fossil fungi remaining microscopic characters are described and annotated. They are identified with the form-genera used by SHEFFY & DILCHER (1971), and are arranged taxonomically with the suprageneric classification proposed by ELSIK (1976). The following notes are added for the Japanese beginners of paleomycology : 1. Fossil records of fungi in the world. 2. Origin and evolution of fungi based on the fossil records. 3. A short historical sketch on paleomycology. 4. Two problems in the classification and nomenclature of fossil fungi. 5. Fungus-like fossils. 6. Nonpetrified fossil fungi.
